ADVANTEST'S NEW WAFER TEST OFFERS BEST 768 DEVICE TEST.


Advantest Corporation has announced availability of its new T5385 memory test system for dynamic random access memory Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically.  (DRAM) wafer test, offering a parallel test capability of 768 devices -- the highest in the industry, and twice the capability of the company's previous model. The T5385 will be available beginning August 2009.

Demands at wafer level test continue to increase for both improved performance and a lowered cost-of-test. Advantest's new T5385 addresses these issues and improves efficiency per device while scaling even higher in parallelism An overlapping of processing, input/output (I/O) or both.

1. parallelism - parallel processing.
2. (parallel) parallelism - The maximum number of independent subtasks in a given task at a given point in its execution. E.g.
. The T5385 not only boasts an unrivaled 768-DUT parallel test capacity, but also delivers 533Mbps capability for increased throughput and lowered test costs, making it an ideal solution for high-volume wafer fabs. The new tester is equipped with a flexible pin configuration that supports diverse DRAM devices, and allows tester pin resources to be optimally allocated for efficiency, reduced touchdowns and improved throughput. The T5385 also delivers Known Good Die (KGD KGD Known Good Die (semiconductor industry)

-- New Tester Improves Throughput in Wafer Test Process

DRAM memory chips used in today's computers and other electronics deliver faster processing speeds See MHz. , higher data storage volumes, and more efficient power consumption than previous generation devices. To enable these gains, the semiconductor industry is aggressively migrating to smaller process nodes that allow more chips and greater densities to be produced from each wafer. Throughput has therefore become a critical issue in DRAM wafer test, with chipmakers demanding significant gains to increase productivity. Advantest's new T5385 delivers an unrivalled parallel test capability and flexible pin configurations that significantly improve throughput in the wafer test process.

-- Features and Benefits (1) Industry's highest DRAM wafer test parallel capability of 768 devices The T5385 boasts a parallel test capability of 768 devices -- twice that of Advantest's previous model, the T5383, and the highest in the industry. Massively parallel See MPP.  testing reduces touchdowns and helps to lower test costs significantly in high-volume wafer fabs. The new tester is also equipped with a flexible pin configuration that supports diverse DRAM devices, allowing tester pin resources to be optimally allocated for greater efficiency. (2) High-Speed MRA Enabled by hardware and software advances, the T5385 offers a high-speed MRA (Memory Repair Analyzer) for DRAM and flash memory wafer test that reduces test time by 30%, compared to the previous model. (3) Reinforced Flash Memory Test Capability The T5385 also supports flash memory wafer test. It boasts a proprietary tester-per-site architecture optimized for flash memory, contributing to reduced test times. (4) T5385ES Memory Test System for DRAM R&D Also Available Designed for engineering use, the smaller T5385ES offers all the functional and performance qualities of the T5385. Engineers can easily perform evaluation and characterization, and test programs developed on the T5385ES can be seamlessly transferred to the T5385, accelerating DRAM development processes.

With the announcement of the T5385ES and T5385 test systems, covering DRAM and flash memory wafer test from development to high-volume production, Advantest again affirms its commitment to providing best-in-class test solutions.

Key Specifications: Target Test Devices: DDR3 / DDR2-SDRAM, NAND (Not AND) A Boolean logic operation that is true if any single input is false. Two-input NAND gates are often used as the sole logic element on gate array chips, because all Boolean operations can be created from NAND gates. See flash memory.  / NOR Flash memory, etc. Parallel Test Capacity: T5385: 768 (x 4 I/O channels See channel. ) T5385ES: 12 (x 4 I/O channels) Maximum Test Speed: 266MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc.  / 533Mbps
